AB - The construction sector plays an important role in economic development, yet construction projects continue to face critical challenges in material procurement and supplier logistics. These challenges can delay material flows, disrupt project schedules, and weaken overall supply chain performance. This study evaluates supply chain performance in an Indonesian toll road construction project using the SCOR 14.0 framework to identify performance gaps and propose improvement strategies that support lean construction. The analysis focuses on supplier reliability, responsiveness, and agility from the contractor’s perspective using the Objective Matrix (OMAX) and Traffic Light System. The results show that reliability was the strongest attribute across suppliers, while responsiveness and agility remained moderate, indicating weaknesses in delivery coordination, production responsiveness, and adaptation to demand changes. The findings suggest that SCOR 14.0 provides a useful project-level framework for evaluating multiple suppliers and identifying strategic recommendations to improve supply chain integration, reduce waste, and support workflow continuity.
